DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water discharging device,
More specifically, the present invention relates to a water discharge device including a water discharge / stop operation unit and a flow control operation unit as a hand operation unit.

[0002]

2. Description of the Related Art In recent years,
As a kitchen faucet device (water spouting device), a device in which the tip end of a water spouting tube is configured as a shower head, which is drawn out together with a shower hose so that water can be spouted from a water spout has come to be used. Alternatively, a hair wash shower faucet provided in a toilet restroom has the same form.

On the other hand, in a bathroom, a shower hose has been conventionally extended from a water faucet body, a shower head is connected to the tip thereof, and water supplied from the water faucet body is discharged from the shower head through the shower head. Widely used.

[0004] In the case of these water discharge devices, the shower head can be freely brought to a target position to discharge water, which is more convenient than other conventional water discharge devices whose water discharge position is almost fixed. However, on the other hand, the water discharge / stop water operation part for performing water discharge / water stoppage (water discharge) from the water discharge port and the flow control operation part for adjusting the water discharge flow rate from the water discharge port are located far from the shower head. , There was a problem that their operation was difficult.

Therefore, for example, in a water spouting device for a bathroom, a shower head is provided with a water spouting operation unit as a hand operation unit. FIG. 14 shows an example. In the figure, 300 is a shower head,
302 is a joint pipe to which each end of a flexible shower hose 304 of a predetermined length is connected. The joint pipe 302 has a connection port 306, and the connection port 306
Is connected to the faucet main body, and water from the faucet main body passes through the main water passage 308 inside the shower hose 304 and the main water passage 308 inside the shower head 300, and the shower head 3
00 is supplied to the spout.

[0006] The shower head 300 is provided with a water discharge and stop operation unit 310 as a hand operation unit, and the main valve 312 for opening and closing the main water channel 308 is opened and closed by operating the water discharge and stop operation unit 310. ing.

More specifically, a flexible tube 314 is inserted inside the shower hose 304 and the shower head 300, and a pilot water passage 316 is formed therein. When the push operation is performed rightward from the state shown in the figure, the pilot valve 322 is separated from the valve seat 324 and opened by the rightward movement of the shaft 318 and the downward pushout of the ball 320, and water in the pilot water passage 316 is removed from the shower head 300. Discharge into the main water channel 308 inside.

Then, a back pressure chamber 326 formed on the back side of the main valve 312 (this back pressure chamber 326
The main valve 312 opens upward in the figure due to the feedwater pressure. Here, water is supplied to the main water passage 308 in the shower hose 304 from the faucet main body side. The supplied water is shower head 30
After flowing through the main water channel 308 inside 0, water is discharged from the water discharge port at the tip.

On the other hand, when the water discharge / stop operation section 310 is pushed to the left to return to the state shown in FIG. 14, the pilot valve 322 is closed here, whereby the pressure inside the back pressure chamber 326 gradually increases, and The main valve 312 is closed, and the supply of water to the water outlet is stopped.

In the water discharging device shown in FIG. 14, the water discharging and stopping operation unit 3 is held while the shower head 300 is held in a hand.
By operating the hand 10, the water can be discharged from the water discharge port, and since the water discharge operation section 310 opens and closes the pilot channel 316, it can be easily operated with a small force. Although it is highly convenient, in this water discharge device, when adjusting the flow rate from the water discharge port, the flow control operation part of the faucet body far from the shower head 300 must be operated. However, it is not yet satisfactory in terms of convenience.

FIG. 15 shows another conventional example. In this example, the valve 33 is rotated by rotating an operation knob 330 of a water discharge / stop operation section 328 provided on the shower head 300.
2 is moved in the axial direction, and the main water passage 308 is opened and closed by contacting or separating the valve seat 334 from the valve seat 334, so that water is discharged from the water discharge port 336 and water is stopped. In the case of the water discharge device of this example, the valve body 332
Is closed, the main valve 312 disposed upstream of the shower hose 304 is also closed.

[0012] Even in the water discharge device of this example, the water can be stopped by hand operation while holding the shower head 300 in hand. However, in the case of this water spouting device, there is a problem that the operation becomes heavy since the water spouting operation section 328 as a hand operation section directly opens and closes the main water passage 308 through which water flows at a large flow rate. When the valve body 332 is closed by operating the water stopping operation section 328, there is a problem that a certain pressure is trapped inside the shower head 300 and the shower hose 304 on the upstream side, and further, the water outlet is further increased. Since the water is kept in a water-stop state with the water accumulated near 336, there is an inconvenience that various germs may be generated and propagated in the retained water.

In the case of the water discharge device shown in FIG. 15, the amount of water discharged from the water discharge port 336 can be adjusted by adjusting the amount of rotation of the operation knob 330 in the water discharge / stop operation section 328. . However, in this case, since both the water discharge and the flow rate adjustment are performed by one operation unit and one valve, the flow rate adjustment must be performed each time the water discharge is performed, and the operation is troublesome. There is a problem. In other words, even if the position of the valve 332 is adjusted so that the flow rate becomes an appropriate flow rate, the position of the valve is inevitably moved when water is shut off thereafter. It is troublesome to operate.

The water discharge device having a shower head has been described as an example. However, in a general kitchen faucet device (water discharge device) which discharges water from the water discharge port at the tip of a normal long water discharge pipe without such a shower head. There is a similar problem that is greater or lesser.

According to a sixth aspect of the present invention, in the water discharging apparatus according to the fifth aspect, the water discharging / stopping operation section includes an operating member which is an input section of an operating force, and the pilot valve each time the operating member is pressed. It is characterized by having a lock mechanism for alternately holding the valve in the valve closing position and the valve opening position.

According to a seventh aspect of the present invention, in the water discharge device according to any one of the first to sixth aspects, the flow adjustment operation unit is a dial type that performs a rotary motion.

According to an eighth aspect of the present invention, in the water discharge device according to the seventh aspect, the flow regulating valve comprises a spool valve.

According to a ninth aspect of the present invention, in the water discharge device according to any one of the first to eighth aspects, the shower head connected to the shower head or the water discharge pipe or the main water passage upstream of a water passage is provided. A main valve is incorporated, and a thin tube extends through the inside of the shower hose or the water passage from a portion where the main valve is provided to a portion where the pilot valve is provided, and the pilot channel is formed in the small tube.

[0026]

As described above, according to the water discharging device of the first aspect, the water discharging and stopping operation part and the flow regulating operation part are separately and operably operated separately in the water discharging part comprising the shower head or the water discharging pipe. In the case of this water discharge device, not only the water discharge from the water discharge port but also the flow rate adjustment can be operated at hand, and the convenience of the water discharge device can be dramatically improved.

In addition, in the case of this water discharging device, the water discharging and stopping operation part and the flow regulating operation part and the corresponding water discharging and stopping valve and the flow regulating valve are provided separately, so that every time the water discharging and stopping operation is performed. This has the advantage that the flow rate must be adjusted each time.

In this water discharge device, when the flow control operation unit is operated so that the flow rate of water discharged from the water discharge port becomes a desired water amount, the water stop operation is performed by the water discharge and stop operation unit while maintaining the state. Therefore, when water is subsequently discharged again, water can be automatically discharged from the water discharge port at a desired flow rate.

According to a second aspect of the present invention, there is provided a water discharge device comprising a main valve for opening and closing a main water passage as the water discharge stop valve and a pilot valve for controlling the operation of the water discharge stop valve. In this water discharge device, the water discharge operation from the water discharge port can be performed lightly with a small operation force. In addition, since the pilot valve and the flow control valve are incorporated inside the water discharge section, the corresponding valves are located near the water discharge and stop operation section and the flow control operation section, and the structure of the operation section and the valve is simplified. And a good assemblability.

Here, the water discharging / stopping operation part and the flow control operation part can be arranged coaxially. In this case, since the operation units are concentrated, the usability is good and the device is compact. In this case, the water discharge operation section is arranged inside and the flow control section is arranged outside,
A pilot valve and a pilot channel opened and closed by the pilot valve can be formed in the center of the water discharge section (claim 4).

In the present invention, the water discharging / stopping operation section may be of a push button type. Since the water discharging and stopping operation unit is merely for performing the water discharging operation and the water stopping operation, that is, for merely performing the on / off operation,
It is easy to make this a push button type, and in such a case, the water discharge and stop operation can be easily performed with one touch.

In this case, the water discharge / stop operation section has an operation member which is an input section of the operation force and a lock mechanism for alternately holding the pilot valve between the valve closing position and the valve opening position each time the operation member is pushed. (Claim 6). With this configuration, the water discharge state and the water stop state can be maintained without continuously applying the pushing force, and the operation is simplified.

On the other hand, the flow adjustment operation unit can be a dial type which performs a rotary motion. Further, the flow regulating valve can be constituted by a spool valve which performs a rotational movement in accordance with the rotation of the flow regulating operation section.

According to the ninth aspect of the present invention, the pilot valve is formed by extending a thin tube from the portion where the main valve is provided to the portion where the pilot valve is provided, and the pilot valve is closed by the pilot valve. When the water is shut off, the shower hose or the main water channel in the water channel can be opened to the atmosphere, so that the shower hose or the main water channel in the water channel can accumulate pressure or accumulate water. Can be avoided well.

In a tenth aspect of the present invention, a shower hose or a pressure reducing valve for reducing the pressure of the downstream portion with respect to the feed water pressure in the main water passage upstream of the water passage and upstream of the main valve is incorporated. In this water discharge device, when the flow control valve is operated by operating the flow control operation unit with the main valve open, specifically when the flow rate is reduced,
It is possible to prevent the inside pressure of the shower hose or the like from becoming excessive due to the water supply pressure, thereby preventing the shower hose portion from becoming hard. This is because the pressure reducing valve throttles or closes the main water passage when the downstream portion is increased in pressure by reducing the flow rate, thereby maintaining the pressure of the main water passage in the downstream portion at a reduced pressure with respect to the feed water pressure. Therefore, even when the flow rate is reduced while the main valve is open, it is possible to satisfactorily prevent a large pressure from accumulating in the downstream portion.

According to the eleventh aspect, the main valve and the pressure reducing valve are incorporated in a joint pipe connected to a shower hose. In this way, the conventional faucet main body needs to be modified at all. And the assemblability of the water discharging device is improved.

The pressure reducing valve 56 has a large-diameter piston portion 58, and the piston portion 58 is slidably fitted on a cylindrical sliding surface 60.

When the pressure of the pressure reducing valve 56 at a downstream portion thereof, more specifically, at a portion downstream of the portion where the pressure reducing valve 56 is provided in the main water passage 36 rises and reaches a constant pressure, pressure receiving between the upstream portion and the downstream portion is performed. Due to the difference in area, the main channel 3 is pushed downward by moving the contact portion 66 closer to or in contact with the valve seat 62 as shown in an enlarged view in FIG.
6 is closed upstream of the throttle or main valve 42.

That is, the pressure reducing valve 56 restricts or closes the main water passage 36 so that the pressure in the downstream main water passage 36 is lower than the upstream (primary side) water supply pressure (pressure reduction state). ). The pressure reducing valve 56
Is normally urged by the spring 64 in the valve opening direction. A threaded connection port 68 is provided at the end of the joint pipe 34.

The shower head 16 incorporates a flow control valve 70 composed of a cylindrical spool valve so as to rotate integrally with the flow control operation unit 24. This flow control valve 7
Numeral 0 is for adjusting the flow rate of water in the main water channel 36, and has an opening 72 that is substantially wedge-shaped in the circumferential direction, that is, an opening 72 whose opening width gradually changes as it advances in the circumferential direction. On the other hand, in the shower head 16 (strictly speaking, on the main body side of the shower head 16), a circular opening 74 that connects the main water channel 36 and the water discharge port 18 is formed.

In this embodiment, water from the main water channel 36 flows out to the water discharge port 18 through the openings 72 and 74. Therefore, as shown in FIG. 11 and FIG.
Is rotated together with the flow control operation unit 24 to change the position of the opening 72, so that the flow rate of water discharged from the water discharge port 18 is changed from large to small or vice versa.

The water discharging / stopping operation section 22 is of a push button type in this example, and has an inverted cup-shaped operation member 76 as shown in FIG. 4, and a pilot water passage 46 each time the operation member 76 is pushed in. Mechanism 80 for alternately holding a pilot valve 78 for opening and closing the valve in a closed position and an open position.
And

The pilot valve 78 has a shaft-like contact portion 82.
When the contact portion 82 contacts the valve seat 86 of the mounting member 84 (see FIG. 10) at the end of the tube 38, the pilot water passage 46 is closed (see FIG. 4A).
Further, the pilot waterway 46 is opened by separating from the valve seat 86 (see FIG. 4B).

In this embodiment, the lock mechanism 80 is of a thrust lock type and has an outer cylinder 88 and a cylindrical guide portion 90 (see FIG. 9) formed so as to protrude from the inner peripheral surface thereof. I have. The guide portion 90 has sawtooth-shaped engaging teeth 92 in the circumferential direction along the upper end surface, and further has a plurality of grooves 94 at predetermined intervals along the circumferential direction.

On the other hand, the pilot valve 78 is provided with a large-diameter fixed ring 96 and a rotating ring 98. The rotating ring 98 is rotatable around the shaft portion 100,
Further, the stopper can be relatively moved up and down by a small stroke between a stopper portion 102 provided on the shaft portion 100 and the fixing ring 96.

Protrusions 104 are provided on the outer peripheral surface of the fixing ring 96 at regular intervals in the circumferential direction, and engagement teeth 106 are formed at the upper ends thereof. On the other hand, the rotating ring 98 is also provided with projections 108 at regular intervals along the circumferential direction, and at the lower end portion of the rotating ring 98 including the projections 108, saw-shaped engaging teeth 110 along the circumferential direction. Are formed.

As shown in FIGS. 3 and 4, the pilot valve 78 is always urged downward by a spring 112 on the upper surface of the rotating ring 98, and the outer cylinder 88 of the lock mechanism 80 is It is always biased upward.

The thrust lock type lock mechanism 8 of this embodiment.
0 works as follows. FIGS. 9B and 9I show a state where the pilot valve 78 is in contact with the valve seat 86 of the mounting member 84 at the end of the tube 38, that is, a state where the pilot water channel 46 is closed.

In this state, when the operating member 76 and the outer cylinder 88 of the lock mechanism 80 are pushed downward against the urging force of the springs 112 and 114, the pilot valve is pushed as shown in FIGS. The rotating ring 98 at 78 is disengaged from the groove 94 of the guide portion 90, where the rotating ring 98 is engaged with the engaging teeth 106 of the projection 104 on the fixed ring 96 and the cam surface of the engaging tooth 110 on the rotating ring 98. Is rotated counterclockwise by a small angle.

Thereafter, when the pushing force is removed, the spring 114
The guide portion 90 moves up together with the outer cylinder 88 by the urging force, and at this time, the engaging teeth 92 at the upper end of the guide portion 90 and the engaging teeth 110 of the rotating ring 98 partially mesh.

When the guide portion 90 is further pushed upward, the rotating ring 98 is lifted from the fixed ring 96 and the rotating ring 98 is further rotated counterclockwise by a small angle due to the action of the cam surfaces of the engaging teeth 92 and 110. As a result, the engagement teeth 92 of the guide portion 90 and the engagement teeth 110 of the rotating ring 98 are completely engaged (see FIG. 9B (II)
I)), the rotating ring 98 and the stopper 1
The entire pilot valve 78 including the rotating ring 98 and the fixed ring 96 is raised to the rising end by the contact action with the upper end 02 and is held at the rising end. That is, the pilot valve 78 is held at the valve open position. Here, the pilot water channel 46 is opened, the piston-type main valve 42 is opened, and water flows through the main water channel 36.

When the operating member 76 is pushed again,
At the same time, the outer cylinder 88 of the lock mechanism 80 and the guide portion 9
0 moves downward, where the engagement teeth 110 of the rotating ring 98 and the engagement teeth 92 of the guide portion 90 are disengaged, and the urging force of the spring 112 engages the engagement of the fixed ring 96 in the pilot valve 78. The teeth 106 and the engaging teeth 110 of the rotating ring 98 come into contact with each other (FIGS. 9B and IV),
(V)), and the guide portion 90 further descends to rotate the rotating ring 9.
When the ring 8 is in the free rotation state, the rotating ring 98 is rotated counterclockwise by a small angle by the action of the cam surfaces of the engaging teeth 106 and 110 of the fixed ring 96 and the rotating ring 98, and the engaging teeth 106 and When the gears 110 are completely engaged, the rotation of the rotating ring 98 stops (FIG. 9).
(B) and (VI)).

Thereafter, by removing the operating force, (VI
As shown in FIG.
When the rotary ring 98 is moved upward by the urging force of the rotary ring 4, the engagement teeth 92 of the guide portion 90 and the rotary ring 9 are lifted.
After the rotation ring 98 is rotated by a small angle due to the action of the cam surface with the engagement teeth 110 of No. 8, the projection 108 of the rotation ring 98 is fitted with the projection 104 of the fixed ring 96 in the groove 94 of the guide portion 90, and subsequently By the urging force of the springs 112 and 114, the projections 104 and 108 fall to the bottom of the groove 94 with the upward movement of the outer cylinder 88 (FIGS. 9B and VIII).
reference). Here, the pilot valve 78 is again in a state of closing the pilot channel 46. Since the lock mechanism itself is conventionally known, further detailed description is omitted here.

As shown in FIG. 4, the seal between the pilot valve 78 and the main water passage 36 is sealed by packing on the inner peripheral surface of a plug 116 (see FIG. 10) provided at the end of the main water passage 36. Is being done.

In the case of the water discharge device of this embodiment, the water discharge / stop operation section 22
5, the pilot valve 78 opens from the closed state shown in FIG. 3 as shown in FIG. 5, where the pilot water passage 46 is opened, and the main valve 42 subsequently opens. As a result, water is supplied to the tip of the shower head 16 through the main water passage 36, and subsequently, the flow control valve 70,
After passing through the openings 72 and 74 of the shower head 16, water is discharged from the water discharge port 18. FIG. 6 shows the state at this time.

In the state shown in FIG. 6, the flow control valve 70 is fully opened, and water is discharged from the water discharge port 18 at the maximum flow rate. Now, in this state, when the flow adjusting operation section 24 is rotated and the opening 72 is gradually narrowed, the flow rate of water discharged from the water discharge port 18 decreases (see FIG. 7 (I)).

FIG. 7 (II) shows a state in which the flow rate of water discharged from the water discharge port 18 is most reduced. In such a state, unless the pressure reducing valve 56 is provided, the primary water supply pressure is guided to the tip of the shower head 16, specifically, to the tip of the main water passage 36, and a large pressure builds up in the shower hose 32. This causes the shower hose 32 to be stiff and hard to bend freely.

However, in the water discharge device of this embodiment, the main valve 4
A pressure reducing valve 56 is provided upstream of the pressure reducing valve 2, and when the pressure inside the main water passage 36 in the downstream portion from the portion where the pressure reducing valve 56 is provided increases, that is, the pressure inside the shower hose 32 increases. When it comes, the pressure reducing valve 56 operates in the valve closing direction,
The main water passage 36 is blocked at the upstream and downstream portions of the throttle or the pressure reducing valve 56.

As a result, the pressure in the main water passage 36 downstream of the pressure reducing valve 56 is maintained at a pressure lower than the feed water pressure by a fixed pressure, and therefore, when the flow rate is reduced while the main valve 42 is open. Also, it is possible to effectively prevent the shower hose 32 from being hardened due to excessive pressure inside the shower hose 32.

In the water discharge device of this embodiment, since the main valve 42 is disposed upstream of the shower hose 32, the water discharge operation of the water discharge / stop water operation section 22 causes the pilot water passage 46.
Is closed to close the main valve 42, thereby stopping the water discharge from the water discharge port 18. Therefore, the main water passage 36 downstream of the main valve 42 in the water stopped state is closed.
The entire interior can be opened to the atmosphere, and it is possible to prevent pressure from accumulating in the shower hose 32 and the main water passage 36 in the shower head 16 and to prevent water from staying.

Further, in this embodiment, since the main valve 42 and the pressure reducing valve 56 are incorporated in the joint pipe 34 connected to the shower hose 32, the conventional faucet main body (mixing section 26) is modified at all. There is no necessity, and the assemblability of the water discharging device is improved.

According to the water discharge device of the present embodiment, not only the water discharge from the water discharge port 18 but also the flow rate adjustment can be operated at hand, and the convenience of the water discharge device can be dramatically improved.

In addition, in the case of this water discharge device, the water discharge / stop operation is performed because the water discharge / stop water operation section 22 and the flow control operation section 24 and the corresponding pilot valve 78 and flow control valve 70 are separately provided. This has the advantage that the flow rate must be adjusted each time.

In this water discharge device, when the flow control operation unit 24 is operated so that the water discharge amount from the water discharge port 18 becomes a desired water amount, the water discharge and stop operation unit 22 is maintained while maintaining the state.
Thus, the water stopping operation can be performed, so that the water can be automatically discharged from the water discharge port 18 at a desired flow rate when the water is discharged again.

In the water discharge device of this embodiment, since the pilot valve 78 for controlling the operation of the main valve 42 is closed to stop the water, the water discharge port 1 can be lightly operated with a small operation force.
8 and the pilot valve 78 and the flow control valve 70 are arranged inside the water discharge section and near the water discharge and stop operation section 22 and the flow control operation section 24. The operation unit and the corresponding valve can be directly operatively connected, and the structure of the operation unit and the valve can be made simple, and the assemblability can be improved.

Further, in the present embodiment, since the water discharging / stopping operation section 22 is of a push button type, the water discharging / stopping operation can be performed very easily with one touch.
